The can closure device for fizzy drinks includes both an outer and an inner element. They are forced together by a toggle arm (1) which is swung over to close the opening. The outer element (6) is formed to cover the opening (18) to be closed. A seal (15) made from an elastic material is fitted on that side of the outer element facing the opening. The inner element (9) has a contact surface (18) for the seal which extends beyond the measurements of the opening, at the ends. |
